MP's concern at BBC Cliff raid 'tip-off'

A former policing minister has said he is concerned that the BBC knew in advance about the recent raid on one of Sir Cliff Richard's homes in relation to an alleged historical sex offence.
The Conservative Nick Herbert added that "when we have a system where police officers or staff think nothing of picking up the phone - either for payment or otherwise - and providing these tip-offs, it suggests that there is a cultural issue, that we do not have sufficient professionalism. That's what Leveson said."
South Yorkshire Police have denied leaking the information, but admit they did co-operate with a BBC journalist whom they say already knew about the investigation.
Sir Cliff, who has not been arrested, strongly denies the allegation.
